# Mill Valley king tides and high water in 2026

> In 2026 (record through Sep 30, 2026), NOAA's San Francisco tide gauge recorded water high enough for FloodRoute's model to put at least one Mill Valley road at risk on 62 days. The highest was 8.38 ft on Saturday, January 3, 2026, 1.25 ft above the tide tables, with 23 roads at risk, including Ryan Avenue, Plymouth Avenue and Park Terrace.

**Estimates, not records of actual flooding.** Each day is NOAA's verified high water at the tide gauge, run through FloodRoute's flood model on today's roads and elevations, in dry weather. Drains, levees, tide gates, rain, road changes and elevation error all mean real conditions differed. Not for property, real-estate, insurance, lending, engineering or legal decisions.
